Computrons per watt

These folks have just introduced an M4 version.

I believe NVIDIA claim their Tegra 2 can do 1080p at

Thanks. I'm pretty sure this isn't in the ARM Cortex class of problem, but I'd love to be proven wrong.

Your best bet is probably a SoC that goes into mobile phones and tablets. Freescale, Samsung and TI make such SoCs.

How much are you going to _do_ to this stream of video that's going by at

I'd go digging on Xilinx and Altera sites, looking for papers on reducing power consumption. Whetever else you do, remember three things: (a), this looks to your humble correspondent like a problem for FPGAs, (b), FPGAs are typically power-hungry, and (c), (b) is strongly affected by the cleverness and dedication of your design team.

Good luck. You're going to have more trouble getting the pixels into and out of your computational device than you will actually manipulating them.

Just say no.

The required refresh takes many watts. Like about 50 to 100. That is a modern display card pushed really hard.

Maybe a cable to a much bigger and more POWERful box.

Other than that is sounds like fun.

If you fancy FPGA route you are better off with Lattice for low power - since they bought Silicon Blue they are way ahead of Altera or Xilinx on ultra low power. You will need to do a lot of work to get to an accurate estimation of FPGA power for your application.

I'd say yes. They want viable plans. They give money to try the most promising plans. There is no need to deliver an actual product. Its about getting paid to do research.
